听力原文：Hello, my name is Hellen Schulz. I've been a family physician for over 30 years. Everyday at work, as a doctor, I treat patients who want to take better care of themselves. I suggest plenty of rest and exercise and of course I always recommend a proper diet. Healthy eating is crucial to a healthy life. That' s why I developed a diet based on my experience in nutrition. Here, I'm providing the tools to succeed through the innovative diet in my new cookbook, "Schulz 300". The Schulz 300 will provide you with 300 pages of healthy, easy to make recipes. To order, call 1800-555-2121. That's 1800-555-2121.
